Description

열경화 처리된 그린 타이어의 적재장치{LOADING APPARATUS FOR GREEN TIRE TREATED COATING}LOADING APPARATUS FOR GREEN TIRE TREATED COATING}

본 발명은 열경화 처리된 그린 타이어의 적재장치에 관한 것으로서, 좀더 상세하게는 그린 타이어와 적재장치인 걸대와의 분리시 이형성을 높이기 위하여 불소수지 코팅제를 적용하므로써, 그린 타이어의 비드부 변형을 방지하고, 반영구적으로 사용할 수 있는 열경화 처리된 그린 타이어 적재장치에 관한 것이다.The present invention relates to a loading apparatus of a heat-cured green tire, and more particularly, by applying a fluororesin coating agent to increase the releasability when separating the green tire from the holder, which is a loading apparatus, to prevent deformation of the bead portion of the green tire. The present invention relates to a thermosetting green tire loading apparatus that can be used semi-permanently.

성형기에서 제조된 그린 타이어는 운반 행거(Hanger)를 이용하여 스프레이 머신으로 이송되어 투명계 외부이형제를 스프레이한 후 그린 타이어 보관을 위해 걸대에 적재하여 가류기 전단까지 운반되어 가류를 실시한다. 이때 그린 타이어는 가류기에 투입전까지 걸대에 적재된 상태로 보관된다. 그린 타이어를 적재하는 걸대는 통상 4단 또는 5단(1단은 수평으로 3개의 그린 타이어를 적재)으로 구성되어 있다. 그린 타이어를 수평으로 적재하고 있어서 그린 타이어의 비드 및 사이드월 부분이 걸대링과 접촉함으로써 접촉면적이 클 뿐만 아니라, 타이어 형태가 점점 커져서 자체 하중에 의해 아래쪽으로 타이어가 눌리면서 접착현상이 발생하여 탈착하기가 곤란한 경우가 발생하며 강제적으로 탈착하는 경우, 그린 타이어의 비드부 변 형이 발생하기도 하며, 심한 경우는 작업자의 손목 및 어깨부위 통증을 유발하는 경우가 있다.The green tire manufactured in the molding machine is transferred to the spray machine using a transport hanger to spray the transparent external mold release agent, and then loaded on a stool for storage of the green tire and transported to the front of the vulcanizer for vulcanization. At this time, the green tires are stored in the rack until they are put into the vulcanizer. The base for loading green tires is usually composed of four or five stages (one stage with three green tires placed horizontally). Since the green tires are loaded horizontally, the bead and sidewall of the green tires come into contact with the hanging ring, and the contact area is large, and the tire shape becomes larger and the tire is pushed downward by its own load. Is sometimes difficult, and when forcibly detached, bead deformation of the green tire may occur, and in severe cases, pain in the wrist and shoulder of the worker may be caused.

종래의 대한민국 특허출원 제2003-0047288호에는 걸대링 부위에 접착방지용 라이너지를 감거나 상온 경화형 실리콘 고무 조성물을 코팅하여 표면을 코팅처리하여 사용한 기술이 기재되어 있으나, 라이너지를 오래 사용할 경우, 라이너지를 감은 부위가 찢어지거나 벗겨져서 라이너지 천이 떨어져서, 타이어 사이드월 부위에 오염되어 가류시 이물입 불량이 발생하며, 상온 경화형 실리콘 고무 조성물은 사용 빈도가 높아짐에 따라 코팅된 실리콘 고무의 표면이 벗겨지거나 긁힘이 생겨 수명이 짧아져 재코팅을 실시할 필요가 생겨서 원가상승의 요인으로 작용하고, 벗겨진 부위가 자체 하중에 의해 아래쪽으로 타이어가 눌리면서 접착현상이 발생하여 탈착하기가 곤란한 경우가 발생하였으며, 또한 벗겨진 부위가 타이어 사이드월 부위에 전이되어 불량을 초래하는 문제가 발생하였다.Conventional Korean Patent Application No. 2003-0047288 describes a technique used by coating an anti-adhesive liner paper on a hanger ring or by coating a surface by coating a room temperature curable silicone rubber composition, but when the liner paper is used for a long time, The part is torn or peeled off, and the liner cloth falls off, which contaminates the tire sidewall area, causing foreign matter defects during vulcanization, and the surface temperature of the coated silicone rubber is peeled off or scratched as the frequency of use increases. As the life is shortened, it is necessary to perform recoating, which is a factor of the increase in cost, and the peeled parts are pushed downward by their own loads, resulting in adhesive phenomenon, and it is difficult to remove them. It is transferred to the tire sidewall area The resulting problem occurred.

특히 하절기 및 습도가 높은 경우에 그린 타이어와 걸대링 표면에서 접착현상이 빈번하게 발생하여 곤란한 경우가 많았다.Especially in the summer and high humidity, the adhesive phenomenon occurred frequently on the surface of the green tire and the hanging ring.

본 발명의 목적은 상기와 같은 문제점을 해결하기 위하여, 그린 타이어를 적재하는 걸대 링의 표면에 불소수지를 코팅 처리하여 그린타이어의 걸대링과의 이형성을 향상시킴으로써 그린타이어가 걸대링과 접합된 부위가 쉽게 이형되어 접착문제 및 이로 인해 발생되는 제반 문제점을 해결할 수 있는 그린 타이어 적재장치를 제공하는 것이다. The object of the present invention is to solve the above problems, by coating the surface of the ring ring for loading the green tire fluorine resin to improve the releasability of the green tire with the ring ring portion of the green tire bonded to the ring ring It is to provide a green tire loading device that can be easily released to solve the adhesion problem and all the problems caused by it.

본 발명의 그린 타이어 적재장치는, 걸대링의 표면이 불소수지 100중량부에 대하여 용제 20∼35중량부, 계면활성제 0.5~3중량부 및 에틸알코올 0.5~3중량부를 포함하여 이루어진 불소수지 코팅제로 코팅된 것을 특징으로 한다.The green tire loading device of the present invention is a fluororesin coating agent, wherein the surface of the holder ring comprises 20 to 35 parts by weight of solvent, 0.5 to 3 parts by weight of surfactant and 0.5 to 3 parts by weight of ethyl alcohol with respect to 100 parts by weight of fluororesin. It is characterized by being coated.

본 발명의 불소수지 코팅제에 사용되는 불소수지는 평균 분자량이 100,000 이상인 중합체인 것이 바람직하다. 불소수지의 예로는 크게 3가지 기본 형태, 즉 PTFE(폴리테트라플루오로에틸렌), FEP(플루오르화 에틸렌프로필렌) 그리고 PFA(퍼플루오로알콕시)를 들 수 있는데, 그 중에서도 높은 내열성(약 316℃)과 매우 낮은 마찰계수와 우수한 내마모성 및 내화학성면에서 유리한 PTFE가 특히 바람직하다.The fluorine resin used in the fluororesin coating agent of the present invention is preferably a polymer having an average molecular weight of 100,000 or more. Examples of the fluororesin include three basic forms: PTFE (polytetrafluoroethylene), FEP (fluorinated ethylene propylene), and PFA (perfluoroalkoxy), among which high heat resistance (about 316 ° C) Particular preference is given to PTFE, which is advantageous in terms of low coefficient of friction and excellent wear and chemical resistance.

본 발명의 불소수지 코팅제에 사용되는 용제는 탄소수 5~10개의 탄화수소계 용제인 것이 바람직하다. 상기 용제는 불소수지 100중량부에 대하여 20~35중량부 사용되는 것이 바람직한데, 용제의 사용량이 35중량부를 초과하는 경우에는 혼화성에는 좋으나 불소 코팅 피막의 내구성이 하락되며, 20중량부 미만인 경우에는 점도가 상승하여 도장 작업성이 하락하고, 또한 경화 작업시 에너지 효율 증가와 내피로 특성이 하락하여 피막에 균열이 발생하여 바람직하지 않다. It is preferable that the solvent used for the fluororesin coating agent of this invention is a C5-C10 hydrocarbon-type solvent. The solvent is preferably used 20 to 35 parts by weight based on 100 parts by weight of the fluororesin, when the amount of the solvent used exceeds 35 parts by weight is good for miscibility, but the durability of the fluorine coating film is lowered, less than 20 parts by weight It is not preferable because the viscosity rises and the coating workability decreases, the energy efficiency increases and the fatigue resistance decreases during the curing operation, resulting in cracks in the coating.

본 발명의 불소수지 코팅제에 사용되는 계면활성제는 그 종류에 특별한 제한이 없으며, 바람직한 예로는 지방산 모노글리세린 에스테르, 지방산 폴리글리콜에스테르, 폴리에틸렌 글리콜 축합형 비이온 계면활성제를 들 수 있다. 상기 계면활성제는 불소수지 100중량부에 대하여 0.5~3중량부 사용되는 것이 바람직한데, 계면활성제의 사용량이 상기 범위를 벗어나는 경우에는 각 성분간의 습윤성이 하락하여 저장안정성이 하락되고, 각 성분간의 분리가 일어나며, 경화 작업시 에너지 효율 증가와 내피로 특성을 평가시 피막에 균열이 발생하여 바람직하지 않다.The surfactant used in the fluororesin coating agent of the present invention is not particularly limited in its kind, and preferred examples thereof include fatty acid monoglycerine esters, fatty acid polyglycol esters, and polyethylene glycol condensed nonionic surfactants. The surfactant is preferably 0.5 to 3 parts by weight based on 100 parts by weight of the fluororesin. When the amount of the surfactant is out of the above range, the wettability between the components is lowered and the storage stability is lowered. It is not desirable to increase the energy efficiency during curing and cracks in the coating when evaluating fatigue properties.

본 발명의 불소수지 코팅제에 사용되는 에틸알코올은 불소수지 100중량부에 대하여 0.5~3중량부 사용되는 것이 바람직한데, 에틸알코올의 사용량이 상기 범위를 벗어나는 경우에는 각 성분간의 습윤성이 하락하여 저장안정성이 하락되고, 각 성분간의 분리가 일어나며, 경화 작업시 에너지 효율 증가와 내피로 특성을 평가시 피막에 균열이 발생하여 바람직하지 않다.Ethyl alcohol used in the fluororesin coating agent of the present invention is preferably used 0.5 to 3 parts by weight based on 100 parts by weight of fluororesin, when the amount of the ethyl alcohol is out of the above range, the wettability between each component is reduced and storage stability This decreases, separation between the components occurs, and the increase in energy efficiency during the curing operation and cracking in the coating when evaluating fatigue resistance are undesirable.

상기와 같은 조성을 갖는 불소수지 코팅제를 그린 타이어 적재장치의 걸대링 표면에 도포하여 본 발명의 그린 타이어 적재장치를 얻는데, 이때 도포하는 방법의 바람직한 일예는 다음과 같다. The fluororesin coating agent having the composition as described above is applied to the surface of the hanging ring of the green tire loading device to obtain the green tire loading device of the present invention, and a preferred example of the coating method is as follows.

우선, 걸대 링의 금속표면에 샌드페이퍼를 이용하여 녹이나 이물질을 제거하고 나서, 용제로 표면을 깨끗이 세척한 후, 약 10분 이내의 시간 동안 건조하고, 스프레이 장치내에서 불소수지 코팅제를 도포한다. First, rust or foreign substances are removed from the metal surface of the hanging ring using sand paper, and then the surface is cleaned with a solvent, dried for about 10 minutes or less, and a fluororesin coating agent is applied in a spray apparatus.

도포된 걸대링은 온도 및 시간이 조절가능한 경화장치내에 넣고, 350~450℃의 온도에서 1~2시간 동안 열경화시키면 걸대링의 표면에 완전히 고착된 불소수지 코팅막을 얻을 수 있다. 상기 열경화 온도가 350℃ 미만인 경우에는 고무와 적재장치간의 마찰에 의해 불소코팅 피막의 안정성이 하락하여 그린 타이어 표면에 피막성분이 전이되어 타이어가 불량하게 되므로 바람직하지 않고, 450℃를 초과하는 경우에는 경화 작업시 에너지 효율 증가와 내피로 특성을 평가시 피막에 균열이 발생하여 바람직하지 않다. The coated ring may be placed in a curing apparatus having a temperature and time control, and thermally cured at a temperature of 350 to 450 ° C. for 1 to 2 hours to obtain a fluororesin coating film completely fixed to the surface of the ring. If the heat curing temperature is less than 350 ℃ undesirably because the stability of the fluorine-coated coating due to the friction between the rubber and the loading device is reduced and the coating component is transferred to the surface of the green tire and the tire is bad, it exceeds the 450 ℃ It is not desirable to increase the energy efficiency during curing and cracks in the coating when evaluating fatigue properties.

이때 얻어지는 코팅막의 두께는 약 50~150㎛의 도막 두께가 가장 좋으며, 두께가 50㎛ 미만인 경우에는 도막의 강도가 나타나지 않아 도막이 쉽게 파괴되며, 150㎛를 초과하는 경우에는 재료의 상승에 의해 원가상승만 증가하게 되어 바람직하지 않다. The thickness of the coating film obtained at this time is the best coating thickness of about 50 ~ 150㎛, if the thickness is less than 50㎛ the coating film does not appear because the strength of the coating film is easily destroyed, if the thickness exceeds 150㎛ due to the rise in cost It is not desirable to increase only.

코팅된 도막의 물성은 로그웰 경도로 58 이상, 인장강도는 150∼250㎏/㎠, 신장율은 300∼800%, 마찰계수는 약 0.4∼0.1 정도인 것이 바람직하다.Physical properties of the coated coating film is preferably logwell hardness of 58 or more, tensile strength of 150 to 250 kg / cm 2, elongation of 300 to 800%, and coefficient of friction of about 0.4 to 0.1.
